Ionically Conductive Elastic Polymer Binder for Ultrahigh Loading Electrode in High-Energy-Density Lithium Batteries. [PDF]

Adv Mater
An ionically conductive elastic polymer (ICEP) binder is introduced for fabricating ultrahigh mass‐loading NCM811 cathodes, offering enhanced elasticity, adhesion, and ionic conductivity for improved structural and interfacial stability. The ICEP‐based ultrahigh loading cathode delivers 377.6 Wh kgcell−1/1016.8 Wh Lcell−1 (including packaging) when ...
